the correct option is answer choice D, because there are multiple 2's in the x column with different f(x) values.
The answer to this is C.54 units² .
Area=1/2 base*height
base=12
height=9
12*9=108
108/2=54
Area=54
The function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.
let the base of the triangle be x
Height of the triangle = x - 4
Area of triangle = 1/2 × base × height
Area = 1/2 × x × (x-4)
Area = 1/2 (x² - 4x)
Area = 1/2 x² - 2 x
We can also write it as a function:
y = 1/2 x² - 2 x
Domain = (3 , ∞)
Range = [0, ∞)
Since 3 is not included in the domain, base of the triangle cannot be 3 cm.
Therefore, the function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.

hope this helps and its right
No nodcause it has to me in y=mx+b form. so just sub. 1 from each side
